so for you it is possible, except that our shooting rate will not be high. I will use a 400cc bottle. If I work with a .22 cal valve, will it work? or do you need a specific valve? thank you for your reaction.
Good morning,I found a 17.5 inch 20 cal LW barrel.I would like to install it on one of my theoben mk2 FAC.I would like to know if I could shoot heavy jsb at 900 fps or is it impossible?Thank you for your answers.
